No. 48,293, now Patent No. o, dated Ilec.25, i962. Eivided and this application lvay 9, 1962, Ser. No. 193,55@ 8Claims. Cl. 22 280) This invention relates to a door latch, and moreparticularly to a rotary bolt door latch for an automobile. rI`his is adivision or" my Patent 3,069,888, issued December 25, 1962, and entitledRotary Bolt Door Latch.

One feature of the invention is that it provides an irnproved doorlatch.

Another feature of the invention is that it provides a door latch havinga dctented rotary bolt and a push button lever for engaging the detentand moving it out of engagement with the latching means, said pushbutton lever being bodily shiftable between an unlocked position whereit moves the detent when it is pivoted by its push button actuatingmeans and a locked position Where the detent is out of the path ofpivoting movement of the push button lever.

A further feature of the invention is that in one embodiment thereof thepush button lever is carried by a pivoted locking lever which may beswung between locked and unlocked positions.

Yet another feature of the invention is that in another embodimentthereof the push button lever is pivotally and slidably mounted on ashalt extending from the latch frame, whereby the push button lever maybe bodily ioved between locked an unlocked positions.

Still another feature ot the invention is that in certain embodimentsthe door may be locked from inside the automobile by turning the remoteoperating handle, while in another embodiment the door may be lockedfrom inside by means of a garnish molding push button, operation of theremote handle serving to shift the latch parts back to unlocked positionand to unlatch the door.

Other features and advantages of the invention will be apparent from thefollowing description and drawings, in which:

FIGURE 13 is a section taken along the line 13 13 of FIGURE l1; and

FIGURE 14 is a `detail section taken along the line l4 ll4 ot FIGURE 13.

Referring now more particularly to the drawings, the automobile showntragmentarily in FIGURE 1 has a body designated generally as l@ and afront door designated generally as l2. The door is hingedly mounted atits front edge on the body in conventional manner (not shown), andadjacent its rear edge the door mounts a latch designated generally asI4 which includes a bolt adapted to engage a striker (not shown) whichis mounted on the body in the jamb tace of the door opening to hold thedoor latched. The general arrangement of this type of bolt and strikerare Well known in the art and, if desired, reference may be had toCockburn et al. Patent No. 2,87l,049 entitled Rotary Gear Bolt DoorLatch to show details of a suitable striker arrangement and its means ofengagement with the bolt. On the outer panel oi' the door there is xedlymounted a gripping handle l5 which carries a push button assembly I6 foractuation of the latch I4 from outside the automobile. Below the handlel5 there is a conventional key cylinder I7 for locking the door fromoutside the automobile. Gn the door inner panel there is a conventionalturn handle IS which is connected by a rod l@ to the latch 1.4 torreleasing the latch and for locking the door from inside the automobile.The automobile also has a rear door 2l which is hingedly mounted at itsfront edge on the body lil and which mounts a latch shown in FIGURES 1lthrough 14. A garnish molding button 22 is connected through a bellcrank 23 and a rod 24 to the rear door latch to lock and unlock the doorfrom inside the car.

FIGURES Z through 5 show the latch parts in detail. The latch has aframe with a body portion 26 which lies along the jamb face iZs of thedoor and is secured thereto by a plurality of bolts 2h, and a flangeportion 3u of the trarne is bent at right angles from the body portion26 thereof .and lies parallel to the door inner panel lib. Latchingmeans rotatably mounted on the body portion 26 of the latch trameinclude a conventional gear type bolt 3l which is rigidly mounted on abolt shaft 32, and a cam or ratchet 34 which is also rigidly mounted onthe shaft 32 so that it is effectively integral with the bolt. The shaft32 is journaled between the frame body 26 and the outer wall of a bolthousing 36 which is carried by the latch trarne and projects out of thedoor through an opening I2C in the jamb face thereof.

The latching means are freely rotatable on the latch frame and arenormally held against rotation in a door opening direction by a detentdesignated generally as 4@ which is pivotally mounted on a rivet 42located above the latching means. The detent has a holding arm 44 whichterminates in a foot 46 adapted to engage any one of the teeth of thecam 34 to hold the latching means against rotation in a door openingdirection. An outside actuator arm 4S projects upwardly from the pivotalmounting of the detent and `an inside actuator .arm Sti projectsinwardly therefrom Iand is received in a slot formed between spaced arms52o .and SZb at the end of a tripper lever designated generally as 52,which is pivotally mounted intermediate its ends on the latch frameflange 3411 by means of a rivet 54. At its other end the tripper lever5?. has an integral curved undogging nger 56 which projects in adirection upwardly and outwardly of the automobile body toward thedetent 49. A tab 5S bent from the under side of the tripper lever at theend thereof is adapted to be engaged by .la remote lever to actuate thetripper lever and disengage the detent foot 46 from the cam 34. A coilspring 6l) connected between the end of the tripper lever and the latchframe biases the tripper lever in a clockwise direction as the partsappear in FIGURES 2 and 3 so that the detent foot 46 is yieldably urgedinto engagement with the cam 34.

A remote lever designated generally as 62 is pivotally mountedintermediate its ends on the flange 3d of the latch frame by means of arivet 64. The end of a downwardly projecting arm 66 of the remote leveris connected to the rod 19 which extends from the inside or remotehandle 18. The remote lever is formed as a bell crank having another arm63 with a tab 7@ turned from its free end at a location where it liesbelow the tab 5S of the tripper lever. Consequently, if the remotehandle 18 is turned in a clockwise direction as the parts appear inFIGURE l to pull on the rod 19, the remote lever 62 will be swung in acounterclockwise .direction and the tab '70 will pick up the tripperlever t'ab 5S to swing the tripper lever in a counterclockwisedirection. Since the slotted end of the tripper lever is connected tothe detent, the detent will be swung clockwise in FIGURE 4 to move itsfoot 46 out of engagement with the cam or ratchet 34 and permit freerotation of the latching means so that the door 12 can be pulled open.

Mounted on the rivet 64 coaxially with the remote lever 62 is a lockinglever designated generally as '72. One arm 74 of the locking leverextends downwardly and forwardly of the automobile body and terminatesin spaced, bent ilanges 74a and 74-b which receive between them a lockactuating crank 76 carried by a shaft 78 connected to the key cylinder17 so that upon turning a key in the key cylinder, the crank '76 may beturned to iip the locking lever between the unlocked position of FIG. 2and the locked position of FIGURE 3. An over center spring 8l) yieldablyholds the locking lever 72 in either position and upwardly extending arm82 of the locking lever is received in a recess 84 formed betweenflanges 86 and 88 bent from the latch frame flange 30 to limit the rangeof pivotal movement of the locking lever.

A pair of ears 90 and 92 are bent outwardly at right angles from theupwardly extending arm S2 of the locking lever and mount between them ashaft 94 of which pivotally supports a push button lever designatedgenerally as 96. A spring 98 is coiled about the shaft 94 and biases thepush button lever outwardly or in a clockwise direction as the partsappear in FIGURE 4. The push button lever has a rearwardly projectingdetent actuating portion 100 and near the upper part of its forward edgethe push button lever is formed with a right angular bent undogging tab102 which normally extends across a projection of the path of swingingmovement of the tripper lever undogging arm S6. A push button shaft 16awhich is connected to and operated by the push button 16 in conventionalmanner is adapted to pivot the push button lever upon actuation of thepush button 18.

With the parts in their normal unlocked position as shown in FIGURES 2and 4, depression of the push button 16 will cause the push button shaft15a to move axially inwardly of the automobile body and pick up the pushbutton lever 96, swinging it in a clockwise direction as the partsappear in FIGURE 4. The detent actuating portion 100 of the push buttonlever will pick up the outside actuator arm 48 of the detent and swingthe detent clockwise so that its foot 46 moves out of engagement withthe cam 34, permitting free rotation of the latch means so that the doormay be opened.

Unlatching from inside the automobile is achieved by turning the remotehandle 18 to pull on the connecting rod 19 and swing the remote lever 62counterclockwise (FIGURES 2 and 3) so that the tab 70 on the remotelever picks up the tab 5S on the tripper lever 52. Since the tripperlever is coupled to theV detent inside actuator arm 50, the detent foot46 will be swung out of engagement with the cam 34.

An important feature of this invention is in the provision of meanswhereby the push button lever 96 may be shifted bodily between anunlocked position illustrated in FIGURE 2 and a locked positionillustrated in FIG- URE 3. When in its locked position the push buttonlever does not pick up the detent when it is pivoted, but instead itmerely free wheels. Locking from outside the automobile may beaccomplished by turning a proper key in the key cylinder 17 so that thecrank 76 flips the locking lever 72 clockwise from the unlocked positionof FGURE 2 to the locked position of FIGURE 3. With the parts in theposition of FIGURE 3, actuation of the push button 16 will merely causethe push button lever 96 to free wheel since the outside actuator arm 48of the detent is out of the path of pivotal movement of the detentactuating portion 1li@ of the push button lever. Locking from inside thevehicle may be accomplished by turning the remote handle 18 in adirection opposite to the direction in which it is turned to open thedoor. Such actuation of the remote handle 22 pushes on the connectingrod 19 to pivot the remote lever 62 in a clockwise direction so that thetab which is bent from the remote lever engages the tab '74a of thelocking lever and swings the locking lever clockwise to its lockedposition. Since the locking lever mounts the push button lever 96, thepush button lever is shifted bodily to its locked position.

The door latch described above incorporates the features of remoteundogging, automatic undogging keyless locking. Remote undogging meansthat when the door is locked from the outside but is opened by means ofthe inside handle 1S, the latch parts are shifted from locked positionto unlocked position so that the operator will not inadvertently belocked out of the car. Automatic undogging means that if the latch partsare shifted to locked position while the door is open, subsequentshutting of the door will cause the parts to be shifted back tounlatched position so that the operator will not inadvertently be lockedout of the automobile. However, if he desires to do so the operator mayaccomplish keyless locking by depressing the outside push button 16 asthe door is closed.

Since the detent 4@ is always coupled to the tripper lever 52, thetripper lever will swing in a counterclockwise direction (FIGURES 2 and3) whenever the detent pivots toward its disengaged position. lf thedoor is slammed shut, the teeth of the bolt .3l will ride overcomplementary teeth on the striker as shown in Cockburn et al. PatentNo. 2,871,049, causing the bolt and the cam 34 to rotate in a clockwisedirection as the parts appear in FIGURES 4 and 5. Upon such rotation thedetent will be cammed over the sloping back side of the cam teeth whichit engages, causing the detent and the tripper lever 52 to pivot. Uponsuch pivotal movement, the undogging inger 56 of the tripper lever willengage the undogging tab 102 of the push button lever and shift the pushbutton lever and the locking lever upon which it is mounted from lockedto unlocked position. The same operation will occur if the tripper leveris swung by turning the inside handle 1S to open the door. The automaticundogging function may be overridden and the door may be locked withouta key if the operator depresses the push button 16 while the door isbeing closed. This operation will swing the push button lever 96 so thatits undogging tab N2 is out of the path of movement of the undoggingiinger 56 of the tripper lever.

In the modified form yof the invention shown in FIG- URES 6-l0, there isno separate locking lever and the push button lever is pivotally andslidably mounted ou a shaft carried on the latch frame. In thisembodiment of the invention the frame has a body portion 126 formed witha right angular ilange 130. The latch bolt 131, bolt shaft l32 and camor ratohet 134 are similar to corresponding parts in the embodiment ofFIGURES 2-5, and the form of the detent 140 is also lthe same,

earners including a holding arm 1Atdterminating in a foot 14d, anoutside actuator arm 14S an inside actuator arm 159. Similarly, there isa tripper lever 152 mounted intermediate its ends on a rivet 154 andbeing coupled to the detent inside actuator arm 15d by means of spacedlingers 1521: and 152i) at one end of the lever. The tripper lever hasan undogging ringer 156 and an actuating flange 158, and coil spring lo@Ibiases the tripper lever and the detent to their normal latch holdingposition. A remote lever designated generally at 162 is pivoted on thelatch frame portion 13d on a stud 164 and is formed with a downwardlyextending arm 166 which is connected to the rod 19 shown in FGURES l, 6and 7. A rearwardly extending arm 163 of the remote lever is formed withan actuating tab 17? for engagement with the complementary tab 153 ofthe tripper lever. An upwardly extending arm 171 of the remote levercarries a bent tab 17in to accomplish inside locking in a manner laterto be described.

The push button lever, which is designated generally as 195, ispivotally and slidably mounted `on a shaft 194 which projects from thebody portion 126 of the latch frame and which also pivotally mounts thedetent 146. A spring 193 performs the double function of biasing thepush button lever in a counterclocltwise direction to an operativeposition as the parts appear in FIGURES S and 9and the iunction orproviding an over center arrangement yieldably to hold the push Ibuttonlever in its locked or unlocked position. rlhe push button lever isformed with a detent actuating arm portion Zoll and with an undoggingtab 262 for engagement with the tripper lever undogging linger E56. Nearits lower end the push button lever 1% is formed with a generallyrectangular opening 15W which receives a crank portion formed at the endof the shaft 178 connected to and operated by the key cylinder 17.

The operation of this embodiment of the latch is generally similar tothe operation of the embodiment described in connection with FGURES 2 6.As far as inside and outside latch release operations are concerned, thetwo species operate in the same manner. Locking is somewhat diiterentbecause instead of providing a separate locking lever upon which thepush button lever is mounted, the lpush button lever is pivotally andslidably mounted on the shaft 194i which projects from the latch frame.ln order to lock the door from the outside a proper liey is turned inthe ley cylinder, swinging the crank portion of the rod 178 to slide thepush button lever 1% bodily on the shatt 19d from the position ofFl-GURE 6 to the position of Elfe-URE 7. ln the locked position of theparts the outside actuator ot the detent is out of the path of pivotingmovement of the detent actuating portion 2d@ or the push button lever.Locking from the inside is accomplished by turning the remote thandle 1Sin the opposite direction from the direction in which it is turned toopen the door. This pushes on the rod 19, swinging the remote lever 162in a clockwise direction (FIGURES 6 7) so that the tab 171e on theremote lever picks the side wall of the push button lever 135 and slidesthe push button lever on the shaft .ld from the position of FIG* RE 6 tothe position of FGURE 7 so that the outside actuator arm 148 of thedetent is out oi the path of swinging movement of the actuating portionof the push button lever 196. The spring 19S yieldably holds the pushbutton lever either in loclred or unlocked position. Automaticundogging, remote undogging and keyless locking may be accomplished inthe same manner as in connection with the embodiment of FGURES 2 6.

FIGURES ll-l4 show another modiiied form of the invention particularlyadapted for use in the rear door of an automobile. ln this niodied formlocking from inside the car is accomplished through a garnish moldingpush button arrangement rather than through operation ofl t'e insideremote handle. The latch illustrated in FGURES ll-lllincludes a framehaving a body portion 21d which lies parallel to the inner panel yof therear door 21 and a right angular tlange 'portion 212 which lies parallelto the iamb face of the rear door and is secured thereto by a pluralityof bolts 214-. A bolt 216 is rigidly mounted on a bolt shaft 21S whichis rotatably journaled between the frame flange 212 and the outer wallof a bolt housing 22d which projects from the frame ut through auopening in the jarnb face of the door. A cam or ratchet 222 is rigidlymounted on the bolt shaft ZES for rotation with the bolt so that thebolt and the cani together comprise latching means.

A detent 224 is pivotally mounted on the frame body 21@ by means of astud 225 and at its lower end the detent is formed with a latching foot224er which is adapted to engage a tooth oi the ratchet 222 and hold thebolt and ratchet against rotation in a door opening direction. Thedetcnt 22d has an upwardly extending arm 22411 for operation by anoutside actuator and an inwardly extending arm 224C for undogging thelatch in a manner later to be described.

A locking lever 212% is pivotally mounted at its lower end on the tramebody 21@ on a stud 23d and at its upper end is connected to the lockingrod 24 which, as shown in FEGURE l, extends to the garnish moldingbutton 22 by way of the bell crank 23. An over center spring 2322 isconnected between the locking lever and the latch frame to yieldablyhold the locking lever either in the unlocked position of FlGURE l1 orin the locked position or FIGURE l2. Intermediate its ends the lockinglever is formed with bent ears 223e and 22d!) between which is mounted apin 23d- =and a push button lever or actuator 236 is `pivotally carriedby the pin. At its upper end the push button lever has a rearwardlyextending nose 23de adapted to pick up the detent 2211. A push buttonshaft Zd@ extends from a door handle push button which is not shown butis conventional in its structure and is similar to the front door handleand push button 15, 1o ot FlGURE l. Upon operation of the rear door pushbutton, the push button shaft Zlll swings the push button lever to pickup the detent and move it out of holding engagement with the latchin-gmeans, assuming that the parts are in the unlocked position of FlGUREll. l the parts are in the locked position of FGURE l2, the push buttonlever 236 merely free wheels upon operation of the rear door push buttonsince the nose 236e of the push button lever vhas been swung so that itspath or" movement no longer intercepts the detent. A spring 2d?. on thepin 234i returns the push button lever to its operative positionillustrated in FIGURE l3 than torce is removed from the rear door pushbutton.

Unlatching from inside the automobile is accomplished through a remotelever 2da which is pivoted on ythe stud 23) on the latch frame. Theremote lever 244 is connected by a rod Zlio to a conventional remoteturn handle on the inner panel of the rear door 21. The remote lever 2deis formed as a bell crank having its free arm overlyirlf7 a portion 243eof a remote connector lever which is pivotally mounted on the frameliange 212 by means of a rivet 2.5i?, being urged toward operativeposi'cn (counterclockwise in FGURE 13) by a spring 25'?, which is coiledabout the stud 25% and has one end bearing against a tab lflb on theremote connector lever and the other end hoolred over the latch frame.At its upper end the connector rever 24S is formed with a bent tab 243Cwhich, when the connector lever is swung in a clockwise direction inFSURE 13 upon operation of the remote handle, picks up the push buttonlever 23o and causes the push button lever to swing the detent foot22de: out of engagement with the ratchet 2,22.

Since the latch of FEGURES ll-lr is a rear door latch, it is desirableto eliminate the remote undogging function as described above inconnection with the latch shown in 2 5 while still retaining the auto-`matic undogging feature.

For this purpose there is an undogging lever 254 which is pivotallymounted on the frame by means of a stud 256 and which is urged by aspring S to the position shown in FGURES 1l and l2. On one side of itspivotal mounting the undogging lever 254 has an arm 254er and on theother side of its pivot there is a second arm 254i? which is formed as adog leg terminating adjacent the edge of the push button lever 236 whenthe locking lever and push button lever are swung to Vtheir rlockedposition which is illustrated in FIGURE l2. In the event the door isslammed shut while the parts-are in the locked position of FIGURE 12,.the detent will swing as its foot 224g cams over the sloping back sideof a tooth of the ratchet 222 while the bolt 216 rolls over the teeth ofthe striker. Downward movement of the undogging arm 224C of the detentwill cause this arm to piclr up the arm 25de of the undogging lever,swinging the undogging lever in a counterclockwise direction in FIGURE12 to shift the push button lever and the locking lever upon which thepush button lever is mounted back to the unlocked position of FlGURE 11.
